Move over brontosaurus, there’s a new bad boy in town — Sefapanosaurus. Wits University and the University of Cape Town are ready to show the world this “new” specimen, although it’s been sitting in storage since 1930.

Dinosaur comes out of closet at South Africa university

Palaeontologists in South Africa have discovered the fossil of a previously unknown dinosaur dating back 200m years. It was found not on a remote desert plain but in a university storeroom.

The specimen had been collected in the late 1930s and for decades it remained hidden among the biggest fossil collection in the country at Wits University in Johannesburg.

More recently it was considered to represent the remains of another South African dinosaur, Aardonyx. But when palaeontologists Dr Alejandro Otero and Emil Krupandan visited the university to look at early sauropodomorph dinosaurs – mostly herbivores with long necks – they saw the bones did not match.

Observing that one of the specimen’s ankle bones is shaped like a cross, the researchers realised they had a “new” dinosaur on their hands. They named it Sefapanosaurus, after the word “sefapano”, which means “cross” in the Sesotho language indigenous to the area where it was dug up.

Krupandan said: “This find indicates the importance of relooking at old material that has only been cursorily studied in the past, in order to re-evaluate past preconceptions about sauropodomorph diversity in light of new data.”
